Embodiment 1

[0034] Such as Figure 1-3 As shown, an air starter motor twin-turbine drive device includes a casing 10 provided with an intake pipe connection port 11 and an exhaust port 12, a primary turbine 20 disposed in the casing 10, a guide wheel 30, and a secondary turbine 40. End cover 50, main shaft 60 and shaft gasket 70. The housing 10 is an axially penetrating housing. The inlet pipe connection port 11 and the exhaust port 12 are arranged front and back, and the inlet pipe connection port 12 is arranged on the shell On the outer wall of the body 10 , an exhaust port 12 is provided at one axial end of the casing 10 .

[0035] Such as Figure 1-2 As shown, the end cover 50 , the primary turbine 20 , the guide wheel 30 and the secondary turbine 40 are sequentially connected to the main shaft 60 , and the primary turbine 20 and the secondary turbine 40 are connected to the main shaft 60 through keys. The shell 10 and the end cover 50 are in clearance fit, and the outer side of the...

Embodiment 2

[0045] This embodiment differs from Embodiment 1 in that: Figure 4 As shown, the injection port 53 and the air intake port 52 are arranged opposite to each other at radial ends of the end cover 50 ; the guide wheel 30 is interference-fitted in the housing 10 .

Abstract

The invention discloses an air starting motor with switchable single turbine and double turbines. The air starting motor comprises a housing, a primary turbine, a guide wheel, a secondary turbine, an end cover and a spindle; the housing is provided with an intake pipe connector and an exhaust port; the primary turbine, the guide wheel, the secondary turbine, the end cover and the spindle are disposed within the housing; the end cover, the primary turbine, the guide wheel and the secondary turbine are sequentially connected to the spindle; one end face of the secondary turbine is provided with a through hole in the axial direction; the guide wheel is also provided with a vent hole; a single turbine and double turbines drive switching bolt is detachably connected to the vent hole. The air starting motor has the advantages that the double turbines can be used or be switched to the single turbine, in order to drive the spindle to rotate; the design is reasonable and the structure is simple; the advantages that the traditional turbine-type air starting motor needs no lubricating gas circuit and is light in weight are retained, and meanwhile, the advantages such as high output power, low gas consumption, high efficiency, high torque, low pressure drop and low starting pressure are provided; switching is achieved just by demounting or mounting the single turbine and double turbines drive switching bolt, and adjusting is convenient and fast.

Description

technical field [0001] The invention relates to the field of air starting motors, in particular to a single-turbine and double-turbine switchable air starting motor. Background technique [0002] The air starter motors widely used at this stage are mainly divided into two types according to the structural form: vane type and turbine type. The vane air starter motor drives the starter motor gear and the engine flywheel to rotate through the compressed air to push the vane to rotate. The vane air starter motor is mainly used in pneumatic tools, high-speed rotating machinery and mining machinery, etc. It has the advantages of explosion-proof, high starting torque, overload protection, small temperature rise, and long-term full-load operation. However, compared with the turbo-type air-starting motor, under the same load capacity, the vane-type air-starting motor is bulky, consumes a lot of air, and has low efficiency. Moreover, the vane air starter motor is noisy and needs air...
